Nianqiao met Qinghe when she was five years old. In her five hundred years, she had never seen a more beautiful fairy than Qinghe.
Nianqiao had to stay with Qinghe for fifteen years, and in the five hundred years she had never seen a ghost more sad than Qinghe.
During the five hundred years of Nianqiao, she prayed for Qinghe's happiness - until the moment she waved her sword to Qinghe.
Qinghe. . . . . . I know you are bound by your promise, so let me cut off your shackles for you, and finally - I will die with you.
